f t The present inventionrelates `to hinges and more particularly to seat hinges.

The main objects of the invention'are to provide a seat hinge for use in conjunction with seats such as opera chairs and the like; to provide a hinge which is adJustable with respecttoarcuate seating; to provide a seat vhinge of the character above indicated which ymaybe readily and conveniently assembled;

and to provide a seat hingeassembly made of `wherein Figure 1 is a fragmentary side elevational view of an opera chair;

' Figure 2 is a sectional view taken on line Y 2-2 of Figure-3;

20. Figure 3 is a sectional view taken on line 1,3-'3 of'Figure 2;

Figure 4 is a sectional view taken on line 4 4 of Figure 2;

" Figures 5 and 6 are perspective views of a yoke lmember and its attaching plate forassembling lthe l hinge to thel `seat supporting channel bar;

Figure 7 is a supporting channel bar;

Figure 8 is a view of a modification of the line 8-8 of Figure 9'; and

Figure 9 is a modificationcof the structure shown in Figure l and taken on line 9-9 of Figure 8.

Referring yto the drawings, a seat end standard comprises a central panel 1 supported by apair of oppositely disposed legs 2, 3.

A pair of cupped members 1, 5 are identically formed, preferably of stamped sheet metal, and each is provided with an axially disposed opening 6, 7. They are secured together adjacent their rims by rivet pins 8, 9

y to form a housing and bearing surface for a friction hinge member hereinafter more fully described. Each of the cupped members are Y Y also provided with three integrally formed earsl() equally spaced from each other about the periphery of the rims of the cupped mem* bers. These ears are provided with bolt orA :standard by screws 11.

' iianges 17, 18.

fragmentary view of the seat screw receiving apertures whereby the hous- A ing is secured to thel panel 1 of the seat end y Nithin the housing formed by the assembled cupped members are a pair of identically formed discs 12, likewise preferably of stamped sheet metal.. These discs are each providedwith peripheral bearing flanges 13,

14, a pair of oppositely disposed arcuate slots k15 concentric with said flanges through which the rivet pins 8, 9 pass, and a centrally disposed non-circular opening 16, here shown as squared, and having laterally disposed squared tubular shaft 19 is of substantially the same size and is secured within'the centrally disposed Aopening ofthe discs by suitable' means such as by spot welding for rotating `the discs' within their housing through an are limited by thermovement of the rivet pins v8, 9 arcuate slots'15. Y

Ay channel bar 20, for supporting a seat 21 secured thereto by suitable means such as screws 22 passing through holesV 23 thereof, isprovided with lug receiving apertures or slots 24 and a yoke 25 and its attaching plate 26 serve as a coupling to secure theA tubular shaft 19 to the channel bar seat supporting member 20. This yoke is provided with in! the lug receiving apertures or slots'24 and are adaptedv to be inserted vtherethrough Yand riveted to the channel bar. A bolt 28 passing through the holes 29, 30 and Y31 ofthe yoke,

kshaft and plate respectively provides ready' and convenient meansv for assembling the structure.

It is frequently desirable to install seats of the opera chair type in arcuate rows. l1t

,will be notedthat theperipheral bearing anges 13, 111 of the discs are of less width than the internal widthof the housing within which they rotate. As shown inrFigure 4C,V 'provision is thus made for installation of within their respective K E50 tegi'ally formed lugs 2? which register with has a pair of identically formedcupped mem- Ior lowering of theseat ,gradually engage the cammed surfaces lO-O of the cupped members 4.1, 5.1. The metalto metal contact of the pins 8,19 against the ends of the slotsl and lthe resulting noise which might occur iii construction shown in Figures l to 4 is thus eliminated by the cam action above described 1 may be readily and conveniently assembled.'

in the modified form shown in Figures 8 and 9..

It Will-thus be seen that the seat hinge here-` in shown and described is vadj ustable with respect to arcuate seating, that the structure and that the seat hinge asiembly can be easily made from stamped sheet inetalwith consequent economical manufacturing cost.

7h-ile but Vone specific embodimentV of this invention has been herein shown and described, it will be understood that numerous details ofthe construction shown may be altered or omitted Withoutfdeparting,from the spirit of this invention as defined the yfollowing claims.

I claim: l'
